Standard or regulation
ENA EREC G100
ENA EREC G100 is the UK Engineering Recommendation for customer export and import limitation schemes used to control power flow at a grid connection point. In EV charging it is relevant to load management, constrained connections, V2G export control and maximum import limitation.
V
Vehicle-to-Building (V2B)
Vehicle-to-Building allows an EV to supply energy to a building or site load through compatible bidirectional charging equipment. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
Vehicle-to-Everything (V2X)
Vehicle-to-Everything (V2X) is an umbrella term for bidirectional EV charging use cases where energy can flow from the vehicle to another load, building, home, grid or wider energy system. It includes V2G, V2H, V2B and V2L depending on the destination of the exported energy.
Vehicle-to-Grid (V2G)
Vehicle-to-Grid allows an EV to export energy back to the electricity grid or support grid services through compatible charging equipment. It is normally assessed alongside DNO requirements, import/export limits, generation, storage and wider site energy management.
Vehicle-to-Home (V2H)
Vehicle-to-Home allows an EV to supply energy to a home through compatible bidirectional charging equipment and electrical controls. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
